Hey guys, lurked here a bit, but now I'm in this new math course right. So anyway it seems like a completely new language to me. There's some discussions about reduced row echelon form in the textbook I'm using. I was taught (before going into the course) that the object was to get leading 1s in a diagonal, then 0's in every other spot. The textbook doesn't seem to corroborate this, instead it only puts zeros above the 1s. Then I check wiki and it states 'reduced row echelon form.... satisfies the additional condition: Every leading coefficient is 1 and is the only nonzero entry in its column, as in this example' but then at the same time it shows a matrix which has nonzeros other than 1 and says its also a reduced row echelon form. https://en.wikipedia.org/wiki/Row_echelon_form Could anyone help clear up some of these initial confusions I'm having?
